Bounce emails not working

[lapena]

Hello,

I've just noticed that if I send a mail to a wrong address, I don't receive back any bounce mail.

In maillog I see the mail coming to the wrong address and this error "Recipient address rejected: User unknown in local recipient table"

I've checked postfix main.cf file :
soft_bounce = yes

Do you know where I could look in order to fix this problem ?


Kindest regards,
lapena
